To all whom t may concern: l l l Be it known that l, HERMAN JANSEN, distiller, residing at Schiedam, the Netherlands, have invented certain new and useful Im provements in Stationery, of which the following is a specification.

My invention relates to stationery and particularly to letter sheets the object of my invention being to provide a letter sheet having on one face thereof, a correspondence field and an address field, said sheet being provided at one edge with a flap by which the sheet may be held when properly folded to inclose the correspondence field and eX pose the address field. y

ln the accompanying drawings,

Figure l is a face view of a correspondence sheet in which my invention is embodied; and

Figs. 2, 3, land 5 are similar views showing the successive folds of the sheet to form the closed and sealed letter illustrated in Fig. 5.

The .invention relates to that type of selfcontained letter sheet which embodies not only a correspondence field, but also an ads dress field and marginal flap means for holding the sheet folded. The special object of the invention is to provide a novel sheet of this character in which the correspondence and address fields are not only on the same side of the sheet (to facilitate the making of copies by `carbon or press) but also so related to each other and to the sheet as a whole that the latter may be folded to present the address field on the outside of the folded sheet, but to conceal the correspondence field within the folded sheet, while the whole may be maintained in folded position by a single flap at one end of the sheet.

Referring to the drawings, the sheet 6 is here indicated as divided longitudinally into thirds, two thirds being occupied 'by the correspondence field wihieh extends the full width of the sheet, and the remaining third having, in only its central portion, an address field 8, both fields being on the same face of the sheet. Outside the address field but within the saine third of the sheet and on the same face, are placed the name and address of the writer. The precise location of this return address on this portion of the sheet is not material, but I have shown Specification of Letters )Patent .l itadjacent the bottom edge of the sheet, in

y Patented Aug.. is, isis. Application led April 18, 1918. Serial No. 229,457.

After the letter and address have been written on the sheet within their respective fields-and this may be done on a typewriter at a single insertion of the sheet, since bothletter and address are on the same face of the sheetthe lower third of the sheet is `folded against the back of the sheet as indicated in Fig. 2. The side margins of the sheet are then folded forward over the correspondence field, these side folds having a transverse extent corresponding to the disfiance between the margins of the sheet and the address field S at one end and the margin of the sheet and the sides of the flap 10 at the other end. lt will be noted that inasmuc-h as this fold occurs after the lower third of the sheetcarrying the address field has been folded upward against the back of the sheet, this address field portion is held snugly against the back of the lower portion of the correspondence field. The third oper- `brings the upper end of the sheet adjacent the line of the first fold and the remaining operation is merely to fold the flap over this bend and downon the address field portion of the sheet, where it is secured by any suitable means-such as by pasting it in place or by applying the postage stamps as shown in Fig. 5.

It will thus be seen that the missive is folded zigzag, the first fold being held in place by the inturned margins which are folded over before the second zigzag fold is made,` while the flap 10 secures the whole.

As above stated, all written or printed matter is confined to one face of the sheet, which is an economy, as well as an advantage from the standpoint of making 'copies Since the fiap l0 need not be gummed, press copies may be made without inconvenience. There is also the obvious economy of time and labor in that no separate envelop is used.

I claim as my inventon:-w A letter sheet comprising at one end a correspondence eld extending substantially the full width of the sheet, and an address 5 eld on the same face atthe opposite end of the sheet but of materially less Width than the sheet, said sheet being longitudinally folded zigzag to leave exposed only that portonof said face which contains the address 10 eld and having the side margins of the correspondence field folded upon the mid portion of the correspondence ield after the first zigzag fold is made, together with an end flap at the end of the Correspondence eld adapted to be folded on and secured to the exposed face of the address field, substantially as described.

In testimony whereof I affix my signature.

HERMAN JANSEN.
